In interviews, Chrissy Metz has revealed that filming certain scenes made her physically ill in showing the unraveling of Kate and Toby's marriage.
The Big Guy in Little Coat joke that "old" Toby did was something that Chris Farley did to David Spade when they were on Saturday Night Live (1975) together. It always got a rise out of Spade so it was incorporated into their movie Tommy Boy (1995).
